436422 - SVG SMIL: Occationally some animations don't start

Status: RESOLVED WORKSFORME

(Core :: SVG, defect)

Description

[Daniel Holbert [:dholbert]]

Occasionally when I load this URL...
  http://www.kevlindev.com/tutorials/basics/animation/svg_smil/index.htm
...the first one or two animated SVGs don't start animating.  The red block just stays at its starting place.

The bug is very intermittent, but I can usually get it to happen within a few minutes by mashing "Ctrl-Shift-R" (sometimes pressing "R" multiple times quickly to force quick reloads -- don't know if that helps).

I see this most often with the first animation, and very occasionally with both the first *and* second animation.  This makes me think that order is significant -- (i.e. it's due to losing track of some sort of per-SVG-document token -- we occasionally lose track of the first token, and we very occasionally will lose track of tokens after that one, in order.)

I haven't yet been able to reproduce the bug with a locally-saved copy, which makes me think that network-related race conditions may be involved.

I'm testing using mozilla-central, with patch-queue from this HG repo:

OS = Ubuntu Linux 8.04

When I load the URL all the animations start.  Ctrl-R restarts the animations.  "Ctrl-Shift-R" always reloads without any animations.

I can not reproduce this issue on my own mozilla-central builds, which include the latest patches attached to bug 216462 and bug 468996.

Is this still an issue?

Thanks for the heads-up, Bill!  This appears to be fixed in my build as well, using the latest patch on bug 216462.  This was probably fixed by one of the recent changes to the timing code in the latest patch there.
